Carlton Leonard Roper was convicted of murder and sentenced to life imprisonment. He appeals and we affirm.

1. The defendant argues that the evidence presented at trial was purely circumstantial and insufficient to prove his guilt beyond a reasonable doubt, and that it failed to exclude every reasonable hypothesis inconsistent with his guilt.

We have held that the correct rule for determining the sufficiency of the evidence in convictions based entirely on circumstantial evidence is that

[q]uestions as to reasonableness are generally to be decided by the jury which heard the evidence and where the jury is authorized to find that the evidence, though circumstantial, was sufficient to exclude every reasonable hypothesis save that of guilt, the appellate court will not disturb that finding, unless the verdict of guilty is unsupportable as a matter of law.

Harris v. State, 236 Ga. 242, 245 ( 223 S.E.2d 643) (1976). In this case the jury was properly charged on the definitions of direct and circumstantial evidence and that a conviction on circumstantial evidence alone requires the exclusion of every reasonable hypothesis except that of the defendant's guilt. In rendering its verdict, the jury found that the state had excluded all reasonable hypotheses except that of guilt. Zant v. Nelson, 250 Ga. 152, 154 ( 296 S.E.2d 590) (1982). After reviewing the evidence in a light most favorable to the prosecution, we find that the evidence is sufficient to have authorized the jury to find that the state excluded all reasonable hypotheses except that of the defendant's guilt, and to have authorized any rational trier of fact to find the defendant guilty beyond a reasonable doubt. Jackson v. Virginia, 443 U.S. 307 ( 99 S.C. 2781, 61 L.Ed.2d 560) (1979).

2. The defendant next argues that the trial court erred in allowing the victim's sister to offer hearsay testimony regarding conversations between her and the victim concerning difficulties between the victim and the defendant since such testimony was irrelevant and served to place the defendant's character in issue. The victim's sister testified that the victim told her that she was worried about unauthorized withdrawals from her bank account, that she suspected that the defendant had made those withdrawals, and that she had confronted the defendant with her suspicions and asked him to move out of the apartment. This testimony deals with prior difficulties between the victim and the defendant. While we agree with the State that such testimony is generally admissible to show the defendant's motive, intent or bent of mind toward the victim, see, e.g., Hales v. State, 250 Ga. 112, 113 ( 296 S.E.2d 577) (1982), the evidence, to be admitted, must be otherwise competent. See, e.g., Lawrence v. State, 257 Ga. 423, 424 ( 360 S.E.2d 716) (1987); Hooten v. State, 256 Ga. 31, 33 ( 343 S.E.2d 481) (1986). In the case before us, the testimony of the victim's sister is hearsay, and as hearsay it cannot be admitted solely on the ground that it concerns prior difficulties; the Georgia Code contains no hearsay exception for statements concerning prior difficulties. The state argues that this testimony is admissible as original evidence under OCGA § 24-3-2 to explain conduct and ascertain motives, an argument which assumes the relevancy of such conduct and motive. Dover v. State, 250 Ga. 209, 213 ( 296 S.E.2d 710) (1982). We do not address this argument, however, because we conclude that the testimony was admissible under OCGA § 24-3-1 (b) "from necessity."

The two prerequisites for the admission of hearsay because of necessity are 1) necessity, and 2) particularized guarantees of trustworthiness. McKissick v. State, 263 Ga. 188 ( 429 S.E.2d 655) (1993). The first prerequisite is satisfied since the victim, who is now unavailable as a witness because she is deceased, made the statement. Id. at 189. As to the second requirement, the declaration of the decedent is admissible when it is coupled with circumstances which attribute verity to it. White v. White, 262 Ga. 168 ( 415 S.E.2d 467) (1992); see also C S Bank of Albany v. Swain, 185 Ga. App. 881, 884 ( 366 S.E.2d 191) (1988) (Beasley, J., dissenting). Here, the statements were made by the victim to a sister in whom she placed great confidence and to whom she turned for help with her problems; considering the totality of the circumstances under which the statements were made, we find that there are sufficient indicia of trustworthiness. The sister's hearsay testimony is, therefore, admissible. Moreover, the testimony of the victim's sister was duplicated by that of another witness, relegating any error in the admission of this evidence to the harmless category. Hooten v. State, supra.

Judgment affirmed. All the Justices concur.
